CU LTIVATOR-TOOTH.

SPECIFICATION forming part of Letters Patent No. 465,358, dated December 1 5,1891.

Application filed September 21, 1891. Serial No. 406,393. (No model.)

To all whom t may concern.-

Be it known that we, VILLIAM H. DAVIS and RUFUS P. I-IOWARD,citizens of the United States, residing at La Crosse, in the State of Visconsin, have invented certain new and useful Improvements in Cultivator-Teeth, ot' which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure l represents a side elevation of au improved cultivator-tooth attached to a suitable standard; Fig. 2, a perspective view ot' the tooth or point detached, and Fig. 3 a rear elevation of the same.

This invention relates particularly to that class of cultivator-teeth adapted to be connected to seeding-machines, of which the patent of J. H. Smitl1,-No. 261,636,dated July 25, 1882, is an example; and ithas for its objects to improve the construction of thev reversible tooth employed in this class of machines. While the improved reversible tooth is particularly adapted for use in connection with seeding-machines, we do not confine ourselves in this respect, inasmuch as it is capable of use in other positions with equal advantage, as will appear.

Referring to the drawings by letter, a designates a standard, which may be of any improved construction and which is curved or conveXed at its lower end to form a seat for the improved reversible tooth b. The reversible tooth b is formed of a blank of suitable sheet metal, approximately diamondshaped, the points of the diamond forming the two cultivating-points. The blank is curved longitudinally to form an arc of a circle and is fitted to the curved seat ot' the standard. About midway the ends of the tooth portions of its opposite side edges are bent or folded abruptly backwardly, forming flanges 11,Which are adapted to embrace the standard and are provided with bolt-holes, in order that they may be secured to the standard by the securing-bolt. This bendingabrupt-ly backwardly mit the collected weeds and trash to more I readily pass the tooth while in operation, the

surface presented to the weeds and traslrbe-l ing considerably reduced in width. In forming the standard-embracing flanges 71 from the body of the tooth it will be observed that the metal is not weakened by cutting it or otherwise. If desired, the working face of one of the points may be made flat transversely, as at b', and the other point may be rounded or convexed transversely, as at b", whereby the operator may adjust the tooth to the character of work to be performed. The tooth is readily reversible by removing the bolt securing it to the standard.

Having thus fully described our invention, what we claim is- Y 1. A double-pointed reversible cultivatortooth having portions of its side edges bent backwardly about midway its ends, forming the narrow connection'l, substantially as described.

2. A double-pointed reversible cultivatortooth curved longitudinally andv formed of an approximately diamond-shaped blank, the bearing-face of one of the points being flat and the other convex, and portions of the body of the tooth being bent backwardly and provided with bolt-holes, substantially as de- VILLIAM H. DAVIS. RUFUS P. HOWARD.
